CAN-FEEDING MECHANISM.

Specification of Letters Patent.

Patented Jamie, 191% Application filed February 18, 1914. Serial No. 819,809.

To all whom it may concern:

Be it known that 1, PAUL 1V,I nmscnnn, a citizen of the United, States, residin in West I-loboken, in the county of H11 son. and State of New Jersey, have invented a new and useful Improvement in Can-Feed.- ing Mechanisms, of which the following is a. specification.

This invention relates to improvements in can feeding mechanism.

The object of the invention is to provide a. simple arrangement wl'iereby cans or other 'articlesmay be fed to a can closing machine of a can feeding mechanisn'rshown in connection with a machine for operating on the cans and embodying my improvements.

In said drawing,tl1e dotted lines 1.0 indicate, diagrammatically, the turret of a machine for fianging or topping can bodies,

11 a stationary table adjacent thereto on to and over which the cans 12 are fed to said machine. 11. by any suitable means (not shown) and are mided to the pockets in the star wheel 13 by which the cans are conveyed around the circular guide 14: in a well known manner. Located between the star wheel 13 and the machine for operating on the cans, is a rotatable four-armed spider 15 fixed t0 the rotatable shaft 16, the spider 15 being located above the table 11 as will be understood. Above the spider 15 is rigidly mounted a plate 17 having a volute or other curved edge 18 so arranged that the distance from the axis of rotation of the shaft 16 to the point where the cans are transferred from the star wheel 13 to the spider 15, as indicated at the point 19, is less than at the point, as indicated at 20, where the Cans are transferred to the rotatable turret.

The cans are fed on to the table A fixed guard or guide rail 21 is provieed which is curved to substantially parallel the curved edge 18 of the plate 1 The cans as advanced by the star wheel 13 are moved relatively slowly and are pickedv up by the arms of the spider 15 and as the cans are advanced by the latter they are gradually and uniformly accelerated in speed to equal that of the more rapidly moving turret ofthe machine for operatin on the cans, this being accomplished, as wil be understood, on account of the fact that the cans are gradually and uniformly moved outwardly farther and farther from the center of: rotation of the spider while they are simultaneously being advanced toward the machine.

The foregoing described mechanism is of will be understood. that various changes and modifications may be made withoutdepart- Y ing from the spirit of the invention, and all such changes and modifications are conteml plated as come within the scope of the claims appended hereto. c l

1. A can feeding mechanism of the character described including, in combination: a sdpportii'ig table; a guidcway above said table and along ,which the] articles arelw adapted to be advanced; an article propelling and gradually accelerating member, movable in a..'path over said table in the guideway, said member being rotatable about an axis perpemlicular to the table and located eccentrically of said guideway, and. a moving can carrier to which the cans are delivered by said accelerating member, sub stantially as specified.

2. A can feeding mechanism of the char acter described including, in combination: a curved guideway along which the articles are adapted to be advanced; a rotatable member having propelling arms extending vanced by the spider, and a can-moving de-' vice having substantially the ultimate accelerated speed of said spider and arranged to receive the cans advanced thereby.

4. A can feeding mechanism of the character described including, in combination:

.edge of said plate and forming therewith a curved guideway along which the articles are adapted to be propelled and gradually accelerated by the arms of saidspider.

8. Thecombination of two can-carrying devices which respectively transport the cans at a slower speed and at a faster speed; and an intermediate can feeding device which receives the cansfroln the slower carrier and delivers them to the faster carrier; said feeding device having means -which causes a gradual acceleration of the 'a stationary table; a uniformly rotatabIe, f

multiple-arm spider for advancing articles over said table; and means for gradu lly:

accelerating the speed of the articles as the same are advanced by the spider, said means including a relatively stationary curved guideway arranged eccentrically to the axis of rotation of the spider, and a can-moving device having substantially the ultimate accelerated speed of said spiderand arranged to receive the cans advanced thereby. 5. A can feeding mechanism, comprising a uniformly rotatable radial. arm., an "am-Z bined therewith means causing the cans to be engaged by sald arm atrpoints nearer to and farther from the center of rotation,

to effect retardation and acceleration of the feeding of the cans, and a can-moving de vice having substantially the ultimate accelerated. speed of said arm and arranged to receive the cans advanced thereby.

6. A can feeding mechanism of the character described including, in combination: spaced curved members forming therebetween a curved guideway for the articles being fed; and means for advancing articles along said guideway and simultaneously ac celerating the speed thereof, said means comprising a member uniformly rotatable about an axis located eccentrically rela ive to said curved members, and a can-mo n'g device having substantially the ultimate accelerated speed of said curved members and arranged to receive the cans advanced thereby.

7 A can feeding mechanism of the character described including, in combination: a stationary table; a multiple-arm spider uniformly rotatable in a plane above said table about an axis perpendicular thereto;

a stationary plate located above said spider and having a curved. edge disposed eccenf the speed of the cans while it is feeding them.

9. The combination of two can-carrying devices which respectively transport the cans at a slower speed and at a faster speed; and an .intermediate can feeding device which receives the cans from the slower car rier and delivers them to the faster carrier; said feeding device having a curved eccentric guide which causes a gradual acceleration of the speed of the cans while it is feeding them,

' 10. The combination of two can-carrying devices which respectively transport the cans at a slower speed and at a faster speed; and an intermediate can feeding spider which receivesthc cans from the slower carrier and delivers them to the faster carrier; said spider-having means which causes a gradual acceleration of the speed of the -cans while it is feeding them. I

11. A can feedingmechanism including, in combination: a rotatable turrefl to which the cans. are to be fed and which thereafter transports them bodily; a stationary table on which the cans are placed and from which they are adapted to slide onto the said turret; a rotary can-feeding device which moves the cans at a speed slower than they are moved by the said turret; a

second rotary can-feeding-device which receives the cans from the first rotary device; and a guiding means which engages the cans while they are moved by the second rotary device and which gradually guides the cans farther from the center of rotation to cause the acceleration of their movement before and when they are delivered to said turret.

12. A can feeding mechanism including, in combination: a rotatable turret to which the cans are to be fed and which thereafter transports them bodily; a stationary table on which the cans are placed and from which they are adapted to slide on to the said turret; a rotary can-feeding device which moves the cans at a speed slower than are moved by the said turret a second rotary can-feeding device which receives the cans from the first rotary device; and a curved eccentric guiding means which engages the cans while they aremoved by the second rotary device and which gradually guides the cans farther from the center of rotationtd cause the acceleration of their movement before and when they are deliyered to said turret,
